  천문 좌표계 변환을 위한 클래스 <br>
  
  <p>용어설명</p>
  <ul>
   <li>황도의 기울기(obliquity of the ecliptic) : 지구의 공전궤도(황도)와 천구의 적도사이의 각
   <li>위도(latitude) : 지구상의 관측지점의 위도
   <li>지방항성시(local hour angle) : 춘분점의 시간각=남중한별의 적경 
   <li>지평좌표계(horizontal coordinate system) : 
    관측지점 기준의 좌표계이다. 북점을 기준으로 천체의 발까지 동적으로 잰 각을 방위각(azimuth), 
    천체의 발부터 천체까지 잰각을 고도(altitude)라고 한다.
    일부 천문학자들은 북점이 아닌 남점을 기준으로 방위각을 재기도 한다.
    이 프로그램은 북점을 기준으로 한다. 
    이 좌표계는 관측자의 기준에서 천체의 위치를 나타내는데 유용하게 쓰인다. 
   <li>적도좌표계(equatorial coordinate system) : 
    지구의 적도를 연장선으로 바라보는 좌표계이다. 
    지구의 회전축을 기준으로 북쪽을 천구의 북극, 남쪽을 천구의 남극이라고 하며
    춘분점으로부터 시계방향으로 천구의 적도를 따라 천체의 발까지 잰각을 적경(right acension),
    천체의 발부터 천체까지 잰각을 적위(declination)이라고 정의한다. 
    이 좌표계는 항성(별)의 위치를 나타내는데 쓰인다.
   <li>황도좌표계(ecliptic coordinate system ) :
    지구의 공전궤도면이 기준면을 황도면이라고 한다. 황도면에 수직인 선을 기준으로 북쪽을 +, 남쪽으로 -로 한다.
    보통 태양계의 행성, 소행성, 혜성등의 위치를 나타낼때 쓰는 좌표계이다.
    지구공전궤도면과 천구의 적도가 만나점을 춘분점, 추분점이라고 하는데 이 중에 승교점(acending note)를 춘분점이라 정의한다. 
    춘분점으로부터 시계방향으로 황도를 따라   천체의 발까지 잰각을 황경(ecliptic longitude),
    천체의 발부터 천체까지 잰각을 황위(ecliptic latitude)라고 한다. 
   <li>은하좌표계(galatic coordinate system ) :
    우리 은하를 기준으로 삼는 좌표계이다. 은하면이 기준면이고 은하의 중심이 기준좌표이다. 
    은하의 기준좌표는 은하의 중심인 적경 17h 42.4m, 적위 -28도 55' 로 한다.
    기준좌표로부터 은하면을따라 시계방향으로 천체의 발까지 잰각을 은경(galatic longitude),
    천체의 발부터 천체까지 잰각을 은위(galatic latitude)라고 한다. 
  </ul>
  
  <p>기능구현에 대해</p>
  <ul>
   <li>단순한 공식이 아닌 행렬변환을 이용했다. 단순한 공식을 사용한다면 1개 값 처리에는 유리하지만 여러개를 처리할 때 쓸데없는 계산을 요할 수 있기 때문이다.
   <li>빠른 계산을 위해 사용할 계수값(황도의 기울기, 관측지점 위도, 지방항성시)을  sin,cos값으로 미리 계산하여 상수화 시켜 사용한다.
   <li>변환행렬은 사용할때 loose하게 만들어진다. 이는 사용하지도 않을 행렬을 미리 만들어 퍼포먼스를 저하시키는 요인을 제거해준다.
   <li>천문학에서 사용하는 중요 4개 좌표계 변환을 모두 수행하도록 만들었다. 
   <li>이 클래스는 클래스를 객체화해서 사용해도 되며 정적함수를 이용해서 사용해도 된다. 
    클래스 객체를 이용하면 더욱 빠른 계산이 가능하며 정적함수를 이용하면 사용되는 행렬을 가져다가 재구성이 가능해진다. 
  </ul>
